Some tests where the ESP (acting as host) will require that a particular test
|
|
device acting as an HID mouse be connected. That test device's information and descriptors are defined in this file.
|
|
|
|
If you are connecting a different HID mouse, please update the descriptor and
|
|
getter functions accordingly.
